What You'll Learn
The KC-10's fuel capacity is 356,000 pounds
The KC-10 is a jet aircraft that can be used for military cargo hauling, aerial refuelling missions, and personnel transport. Its maximum fuel capacity is 356,000 pounds (approximately 161,000 kg). This is nearly double the capacity of the KC-135, which can hold about 183,000 pounds of fuel. The KC-10's six fuel tanks enable it to carry this substantial fuel load.
The KC-10's fuel capacity gives it an impressive range. With cargo, it can fly up to 4,400 miles without refuelling. This range can be further extended through aerial refuelling by another KC-10 or a KC-135. The KC-10's ability to refuel while in the air significantly enhances its operational flexibility and endurance.
The KC-10's fuel system is designed for efficient refuelling of other aircraft. It can deliver fuel at a rate of up to 1,100 U.S. gallons (approximately 4,200 litres) per minute using its centreline refueling boom. Additionally, its hose-and-drogue system has a maximum fuel offload rate of 470 U.S. gallons (about 1,800 litres) per minute. This system allows for the refuelling of a diverse range of aircraft, including those from the Navy and Marine Corps, showcasing the KC-10's versatility in supporting various military branches.
The KC-10's fuel capacity and refuelling capabilities have proven invaluable in military operations. During Operations Desert Shield and Desert Storm in 1991, the KC-10 played a pivotal role in facilitating the deployment of tactical, strategic, and transport aircraft to Saudi Arabia. The ability to carry a large fuel load and refuel multiple aircraft in one mission made the KC-10 essential for the rapid airlift of materiel and forces during these campaigns.

It has six fuel tanks
The KC-10 is a tanker aircraft with a maximum fuel capacity of 356,000 pounds (161,000 kg). It is designed to refuel other aircraft and can carry almost twice as much fuel as the KC-135. The KC-10 has six fuel tanks located in the baggage compartments below the main deck, which contribute to its impressive fuel capacity.
The KC-10's fuel capacity allows it to refuel a wide variety of military aircraft within the same mission. It can utilise either an aerial refueling boom or a hose and drogue system. The refueling boom can deliver fuel at a maximum rate of 1,100 gallons (4,180-4,200 liters) per minute, while the hose and drogue system has a maximum rate of 470 gallons (1,786-1,800 liters) per minute.
The KC-10's fuel capacity and refueling capabilities have been crucial in various military operations. During Operations El Dorado Canyon, Desert Shield, and Desert Storm, the KC-10 played a key role in facilitating the deployment of aircraft, troops, and cargo. The aircraft's ability to carry a substantial fuel load enables it to support extended missions and enhance the operational range of the refuelled aircraft.
The KC-10's design is based on the civilian DC-10, and it has been in service with the U.S. Air Force since 1981. Modifications have been made over the years to enhance its capabilities, including the addition of wing-mounted pods to improve aerial refueling. The KC-10's combination of fuel capacity and versatility makes it a valuable asset for aerial refueling and military operations.

It can refuel a wide variety of aircraft
The McDonnell Douglas KC-10 Extender is an American tanker and cargo aircraft that was operated by the United States Air Force (USAF) from 1981 to 2024. The KC-10 is largely based on the design of the civilian DC-10-30CF, a convertible cargo/passenger transport variant with an extended range compared to the baseline DC-10-10. The KC-10 has both a centerline refueling boom and a drogue-and-hose system on the starboard side of the rear fuselage. The refueling boom can deliver fuel to a receiver aircraft at a maximum rate of 1,100 U.S. gallons (4,200 liters) per minute, while the centerline drogue system has a maximum fuel offload rate of 470 U.S. gallons (1,800 liters) per minute.
The KC-10's six fuel tanks can carry more than 356,000 pounds (161,000 kg) of fuel, nearly double the KC-135's capacity. This increased fuel capacity allows the KC-10 to refuel a wide variety of aircraft, including Navy, Marine Corps, and most allied aircraft, all in one mission. The KC-10 played a key role in the mobilization of US military assets, taking part in overseas operations far from home, such as Operation Eldorado Canyon in 1986, the Gulf War with Iraq in 1990-91, and the War in Afghanistan (Operation Enduring Freedom).
The KC-10's ability to refuel a wide variety of aircraft was a significant advantage during these operations. For example, during Operation Eldorado Canyon, the KC-10s and KC-135s allowed 29 F-111s and other Air Force and Navy aircraft to reach their targets. Similarly, during Operations Desert Shield and Desert Storm, the KC-10 facilitated the deployment of tactical, strategic, and transport aircraft to Saudi Arabia, conducting about 51,700 separate refueling operations and delivering 125 million gallons (475 million liters) of fuel.
The KC-10's versatility in refueling different types of aircraft was a critical factor in its selection for these missions. Its ability to refuel multiple aircraft in a single mission enhanced its operational efficiency and effectiveness. The KC-10's role in aerial refueling and cargo transport contributed significantly to the success of these military operations.

It can deliver 1,100 gallons of fuel per minute
The McDonnell Douglas KC-10 Extender is a jet aircraft that can carry out aerial refuelling missions, transport cargo and personnel simultaneously. It is based on the civilian DC-10 commercial aircraft and has been in service with the U.S. Air Force since 1981.
The KC-10 has a maximum fuel capacity of 356,000 pounds (161,000 kg), nearly double that of the KC-135. This fuel can be used for refuelling other aircraft, and the KC-10 can itself be refuelled by a KC-135 or another KC-10A to increase its range.
The KC-10's refuelling system includes a centreline refuelling boom and a hose-and-drogue system. The boom operator sits in the rear of the aircraft and controls the refuelling process through a digital fly-by-wire system, with a wide window allowing them to monitor the operation.
During refuelling operations, the KC-10 can deliver fuel to a receiver aircraft at a maximum rate of 1,100 U.S. gallons (approximately 4,180-4,200 litres) per minute. This high rate of fuel transfer is a key capability of the KC-10, enabling it to efficiently support military aircraft during missions. In comparison, the hose and drogue system has a lower maximum fuel offload rate of 470 gallons (approximately 1,786-1,800 litres) per minute.
The KC-10's ability to deliver 1,100 gallons of fuel per minute makes it a valuable asset for aerial refuelling operations, contributing to the successful completion of various military missions.

It played a key role in Operations Desert Shield and Desert Storm
The KC-10 has a maximum fuel capacity of 356,000 pounds (161,000 kg) of fuel. This large capacity has been used in support of several military operations, including Operations Desert Shield and Desert Storm.
The KC-10 played a key role in these operations, which took place in 1991 during the Gulf War with Iraq. In the early stages of Operation Desert Shield, aerial refueling was critical to the rapid airlift of materiel and forces. The KC-10, along with the smaller KC-135, facilitated the deployment of tactical, strategic, and transport aircraft to Saudi Arabia. They also moved thousands of tons of cargo and thousands of troops in support of the massive buildup.
During the operations, the KC-10 and KC-135 conducted about 51,700 separate refueling operations and delivered 125 million gallons (475 million liters) of fuel without missing a single scheduled rendezvous. This was described as the "largest air refueling operation in history" by retired Lt. Gen. Pat Caruana, who also stated that "without the phenomenal tanker support we had for the war, we could not have accomplished what we did".
In addition to its refueling capabilities, the KC-10 also contributed to the success of the air war by providing life-saving fuel to warfighters executing global reach. The KC-10's ability to refuel Navy, Marine Corps, and most allied aircraft in a single mission further demonstrated its versatility and strategic importance during these operations.
